California utility drops Arizona leg of planned line

ROSEMEAD, CALIFORNIA
- A California utility said it is dropping plans to build a high-voltage transmission line across the southwestern Arizona desert and is scaling back the project to only its California portion, at least for now.

Southern California Edison said it's halting separate efforts to win approvals from Arizona and federal regulators. The project had been approved by California regulators but rejected initially by the Arizona Corporation Commission.

Rosemead, Calif.-based Edison had taken preliminary steps toward a formal application for the Devers-Palo No.2 project with the Federal Energy Regulatory Commission.

That move was the first by a U.

S. utility under a 2005 federal law that allows federal regulators to approve a transmission line even if state regulators rejected it.

The full 270-mile line would have stretched from the Palm Springs area of California to near the Palo Verde Nuclear Generating Station west of Phoenix in Arizona.

Changed circumstances reduce the project's projected economics benefits, Pedro J. Pizarro, executive vice president of power operations, said in a letter to an Arizona regulator.

The factors are anticipated new energy generation projects in California, lower fuel prices and reduced growth for power demand, Pizarro said. "This analysis reveals that the Arizona portion of the project today cannot be justified as an economic investment funded by California consumers," he said.

However, Edison will resume consideration of the Arizona portion of the project "if further analysis supports the approach," Pizarro added.

Arizona Corporation Commission members had balked at the project, saying it had economic and environmental drawbacks for their state. Those included the prospect that increased demand for Arizona-generated power would hike prices for in-state consumers.
